Description

本発明は、正立時でも倒立時でも円滑に噴射可能な手動式スプレー装置に関する。   The present invention relates to a manual spray device capable of smoothly injecting both upright and upside down.

手動式スプレー装置は、一般的に液体を噴射ポンプへ供給する送液管端部が容器底部に備わり、容器内の液体が減少した状態で容器を逆さにして使用すると、液体が容器頭部へ移動する。その結果、送液管は気体を吸い込み液体噴射作業ができない場合がある。そのため、正立時でも倒立時でも使用可能な手動式スプレー装置が従来技術として種々検討されている。   The manual spray device generally has a liquid supply pipe end portion for supplying liquid to the injection pump at the bottom of the container. When the container is turned upside down with the liquid in the container reduced, the liquid is transferred to the container head. Moving. As a result, there are cases where the liquid feeding pipe sucks gas and cannot perform the liquid jet operation. For this reason, various types of manual spray devices that can be used both upright and upside down have been studied as conventional techniques.

特許文献１は、送液管端部に錘体を取り付け、倒立時に錘体の重みで軟らかい送液管を容器頭部へ移動させるため、液体が入った容器を上下逆さにしても噴射ができる。   In Patent Document 1, a weight body is attached to an end portion of a liquid feeding pipe, and a soft liquid feeding pipe is moved to the container head by the weight of the weight body at the time of inversion, so that even if the container containing the liquid is turned upside down, injection can be performed .

特開２００１−１５８４８８JP 2001-158488 A

しかしながら、使い勝手を考慮して容器頭部を細く括れた構造にすると（図５）、容器内の液体が減少したときに錘体が括れ部に係止し、送液管端部が気体に露出して液体を噴射できない場合がある。   However, if the structure of the container head is narrowed for ease of use (FIG. 5), the weight is locked to the constricted part when the liquid in the container is reduced, and the end of the liquid supply pipe is exposed to the gas. In some cases, the liquid cannot be ejected.

本発明は、このような状況を鑑みてなされたものであり、容器の構造を複雑化しても、正立時でも倒立時でも傾斜時でも円滑に噴射可能な手動式スプレー装置を構成することを目的とする。   The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a manual spray device that can smoothly inject even when the container structure is complicated, upright, inverted, or inclined. And

上記課題を解決するために、本発明は、容器底部から液体を吸引する第１の噴射経路と、容器頭部から液体を吸引する第２の噴射経路と、第１の噴射ポンプと、及び第２の噴射ポンプと、を備える手動式スプレー装置であって、前記第１の噴射ポンプ及び前記第２の噴射ポンプの軸心が同軸に配置される、ことを特徴とする、手動式スプレー装置である。   In order to solve the above problems, the present invention provides a first injection path for sucking liquid from a container bottom, a second injection path for sucking liquid from a container head, a first injection pump, A manual spray device comprising two injection pumps, wherein the first injection pump and the second injection pump are arranged coaxially with each other. is there.

本発明によれば、送液管の移動を考慮する必要がないため、容器の構造を複雑化しても、正立時でも倒立時でも傾斜時でも円滑に噴射可能な手動式スプレー装置を提供することができる。   According to the present invention, since it is not necessary to consider the movement of the liquid feeding pipe, a manual spray device capable of smoothly injecting even when the container structure is complicated, upright, inverted, or inclined is provided.

はじめに従来技術の問題点について図面などを参照して説明する。   First, problems of the prior art will be described with reference to the drawings.

（従来技術）
図５を参照して、従来技術の一例を説明する。手動式スプレー装置１００において、正立時の容器１０１内の液体１０２は外部の動力により、容器１０１内の送液管１２３を介して容器底部１０３からポンプ部１１２に供給、加圧され、噴射孔１１１から容器１０１外部に噴射される。容器１０１内の液体１０２は重力により、容器底部１０３に位置するが、容器１０１を逆さにした場合、液体１０２は容器底部１０３から噴射孔方向の容器頭部１０４に移動するため、容器底部１０３の気体１０６を吸い込み液体噴射作業ができない場合がある。 (Conventional technology)
An example of the prior art will be described with reference to FIG. In the manual spray device 100, the liquid 102 in the container 101 in the upright state is supplied and pressurized from the container bottom 103 to the pump unit 112 via the liquid feeding pipe 123 in the container 101 by external power, and the injection hole 111. To the outside of the container 101. The liquid 102 in the container 101 is located at the container bottom 103 by gravity, but when the container 101 is turned upside down, the liquid 102 moves from the container bottom 103 to the container head 104 in the injection hole direction. There is a case where the liquid 106 cannot be sucked in by the gas 106.

このため、従来技術では液体１０２の吸入口である送液管端部１２４に錘体１０７を備え、重力により、容器１０１内の送液管１２３を湾曲させ、送液管端部１２４を液体内に浸漬させ液体１０２を吸引している。しかし、この技術では、使い勝手を良くするため容器頭部１０４を細く括れた構造に設計した場合、容器内の液体１０２が減少すると、倒立時に錘体１０７が括れ部１０５に係止して液体１０２に到達できない。そのため、送液管端部１２４が気体１０６に露出し、液体１０２を噴射できない場合がある。   For this reason, in the prior art, the weight 107 is provided in the liquid feeding pipe end portion 124 which is the suction port for the liquid 102, the liquid feeding pipe 123 in the container 101 is bent by gravity, and the liquid feeding pipe end portion 124 is placed in the liquid. The liquid 102 is sucked by being immersed in the liquid. However, in this technique, when the container head 104 is designed to be narrow and constricted for ease of use, when the liquid 102 in the container decreases, the weight body 107 is locked to the constricted portion 105 when inverted, and the liquid 102 Cannot reach. Therefore, the liquid feeding pipe end 124 is exposed to the gas 106 and the liquid 102 may not be ejected.

次に本発明を実施するための形態について図面などを参照して説明する。   Next, modes for carrying out the present invention will be described with reference to the drawings.

（実施形態１）
図１は、正立時の手動式スプレー装置１０の断面図である。また、図２は図１の左側面図である。手動式スプレー装置１０は、容器底部１０３から液体１０２を吸引するための正立用噴射経路５１及び容器頭部から液体１０２を吸引するための倒立用噴射経路５２の二経路（図４にて詳細を説明する）を備え、これらの二経路へ送液するための正立用噴噴射ポンプ１２及び倒立用噴射ポンプ１３を更に備える。また、正立用噴射経路５１及び倒立用噴射経路５２は、送液端部ａ２４を有する送液管a２３、送液端部ｂ３５を有する送液管b３４、吸入弁a２０、吸入弁ｂ３１、排出弁a１９、排出弁b３０、握りレバー１４及び噴射孔１１を備える。 (Embodiment 1)
FIG. 1 is a cross-sectional view of a manual spray device 10 in an upright state. FIG. 2 is a left side view of FIG. The manual spray device 10 has two paths (detailed in FIG. 4): an upright injection path 51 for sucking the liquid 102 from the container bottom 103 and an inverted injection path 52 for sucking the liquid 102 from the container head. And an upright injection pump 12 and an inverted injection pump 13 for feeding the liquid to these two paths. The upright injection path 51 and the inverted injection path 52 include a liquid supply pipe a23 having a liquid supply end a24, a liquid supply pipe b34 having a liquid supply end b35, a suction valve a20, a suction valve b31, and a discharge valve. a19, discharge valve b30, grip lever 14 and injection hole 11 are provided.

正立用噴噴射ポンプ１２及び倒立用噴射ポンプ１３はピストンポンプである。正立用噴噴射ポンプ１２は、シリンダーａ１６及びピストンａ１７から構成される。倒立用噴射ポンプ１３は、シリンダーｂ２６及びピストンｂ２７から構成される。これらのピストンポンプは、図２に示す様に同心円状の部材から構成され、正立用噴噴射ポンプ１２は外輪から構成されるポンプ機構であり、倒立用噴射ポンプ１３は内輪から構成されるポンプ機構である。正立用噴噴射ポンプ１２及び倒立用噴射ポンプ１３の軸心は同軸に配置される。これらをスプレー作業に支障の無い限られた空間内に組込むことにより、従来の倒立時又は傾斜時作業に噴射困難となる問題点を解決することができる。   The upright jet pump 12 and the inverted jet pump 13 are piston pumps. The erecting injection pump 12 includes a cylinder a16 and a piston a17. The inverted injection pump 13 includes a cylinder b26 and a piston b27. These piston pumps are composed of concentric members as shown in FIG. 2, the upright jet pump 12 is a pump mechanism composed of an outer ring, and the inverted jet pump 13 is a pump composed of an inner ring. Mechanism. The axial centers of the upright injection pump 12 and the inverted injection pump 13 are arranged coaxially. By incorporating these in a limited space where there is no hindrance to the spraying operation, it is possible to solve the problem that it becomes difficult to inject the conventional work during inversion or tilting.

正立時、手動式スプレー装置１０の容器１内の液体２は容器底部３に溜っている。手動式スプレー装置１０は、人力等により外部エネルギーを与えられて握りレバー１４を図１において右方向に移動加圧され、ピストンポンプ用バネ１５（以下バネ１５と称する）が圧縮されてエネルギーを蓄積する。この動作によりシリンダーａ１６に緩やかに嵌合するピストンａ１７が移動し、シリンダーａ１６内の空間を減少させ、残留液体２及び気体６を押出し開孔部ａ１８及び排出弁ａ１９を経て噴射孔１１から外部に排出する。   When standing upright, the liquid 2 in the container 1 of the manual spray device 10 accumulates in the container bottom 3. The manual spray device 10 is given external energy by human power or the like, the grip lever 14 is moved and pressurized in the right direction in FIG. 1, and a piston pump spring 15 (hereinafter referred to as a spring 15) is compressed to accumulate energy. To do. By this operation, the piston a17 that gently fits into the cylinder a16 moves, the space in the cylinder a16 is reduced, the residual liquid 2 and the gas 6 are pushed out, and through the opening portion a18 and the discharge valve a19, from the injection hole 11 to the outside. Discharge.

その後、握りレバー１４を解放することにより、バネ１５は伸延し、噴射孔１１から逆流する液体２又は気体６を排出弁ａ１９で阻止し、シリンダーａ１６内に負圧を生じさせて開孔部ａ１８より液体２または気体６を吸入する。   Thereafter, when the grip lever 14 is released, the spring 15 extends, and the liquid 2 or the gas 6 that flows backward from the injection hole 11 is blocked by the discharge valve a19, and a negative pressure is generated in the cylinder a16, thereby opening the hole a18. Inhale liquid 2 or gas 6 more.

この吸引力によりバネｂ（１９−１）に付勢された吸入弁ａ２０のボールａ２１を吸引し、吸入弁ａ２０の通路ａ２２を開放し、容器１内の送液管ａ２３内の圧力を負圧にする。当該負圧力により容器底部３に位置する送液管端部ａ２４から、大気圧に加圧された容器１内の液体２を吸引する。この吸引力により、シリンダーａ１６内に液体２が充噴される。再び握りレバー１４を図１の右方向に移動加圧するとシリンダーａ１６内に充噴された液体２が加圧され開孔部ａ１８を通り、吸入弁a２０の通路a２２から僅かに遊離したボールa２１を、ラビリンス効果及び液体圧力によって加圧し、吸入弁a２０の通路a２２方向に移動させる。その結果、吸入弁ａ２０の通路ａ２２を密閉し容器１側に逆流することを阻止する。加圧された液体２は排出弁ａ１９を押し上げ噴射液誘導管２５に送り出され、噴射孔１１から外部に噴射される。   With this suction force, the ball a21 of the suction valve a20 urged by the spring b (19-1) is sucked, the passage a22 of the suction valve a20 is opened, and the pressure in the liquid feeding pipe a23 in the container 1 is negative. To. Due to the negative pressure, the liquid 2 in the container 1 pressurized to atmospheric pressure is sucked from the liquid feeding pipe end a24 located at the container bottom 3. Due to this suction force, the liquid 2 is injected into the cylinder a16. When the grip lever 14 is moved and pressurized to the right in FIG. 1 again, the liquid 2 charged in the cylinder a16 is pressurized and passes through the opening a18, and the ball a21 slightly released from the passage a22 of the suction valve a20 is released. Then, it is pressurized by the labyrinth effect and the liquid pressure, and is moved in the direction of the passage a22 of the suction valve a20. As a result, the passage a22 of the suction valve a20 is sealed to prevent backflow to the container 1 side. The pressurized liquid 2 pushes up the discharge valve a <b> 19, is sent out to the jet liquid guide pipe 25, and is jetted to the outside from the jet hole 11.

図３は、倒立時の手動式スプレー装置１０の断面図である。手動式スプレー装置１０の容器内の液体２は容器頭部４に溜っている。手動式スプレー装置１０は、人力等により外部エネルギーを与えられ、握りレバー１４を図示左方向に移動加圧され、バネ１５が圧縮されてエネルギーを蓄積する。この動作によりシリンダーｂ２６に緩やかに嵌合するピストンｂ２７が移動し、シリンダーｂ２６内の空間を減少させ、残留液体２及び気体６を押出し開孔部ｂ２８及び円周溝部２９及び排出弁ｂ３０を経て、噴射孔１１から外部に排出する。   FIG. 3 is a cross-sectional view of the manual spray device 10 when inverted. The liquid 2 in the container of the manual spray device 10 is accumulated in the container head 4. The manual spray device 10 is given external energy by human power, etc., the grip lever 14 is moved and pressurized in the left direction in the figure, and the spring 15 is compressed to accumulate energy. By this operation, the piston b27 that gently fits into the cylinder b26 moves, the space in the cylinder b26 is reduced, the residual liquid 2 and the gas 6 are pushed out, through the opening b28, the circumferential groove 29 and the discharge valve b30, It discharges to the outside from the injection hole 11.

その後、握りレバー１４を解放することにより、バネ１５は伸延し、噴射孔１１から逆流する液体２または気体６を排出弁ｂ３０で阻止し、シリンダーｂ２６内に負圧を生じさせ、開孔部ｂ２８より液体２または気体６を吸引する。この吸引力によりバネｂ（３０−１）に付勢された吸入弁ｂ３１のボールｂ３２を吸引し、吸入弁ｂ３１の通路ｂ３３を開放し、容器１内の送液管ｂ３４内の圧力を負圧にする。   Thereafter, when the grip lever 14 is released, the spring 15 is extended, and the liquid 2 or the gas 6 that flows backward from the injection hole 11 is blocked by the discharge valve b30, and a negative pressure is generated in the cylinder b26. The liquid 2 or the gas 6 is sucked more. With this suction force, the ball b32 of the suction valve b31 urged by the spring b (30-1) is sucked, the passage b33 of the suction valve b31 is opened, and the pressure in the liquid feeding pipe b34 in the container 1 is negative. To.

当該負圧力により容器頭部４に位置する送液管端部ｂ３５から、大気圧に加圧された容器１内の液体２を吸引する。この吸引力により、シリンダーｂ２６内に液体が充噴される。再び握りレバー１４を図示上左方向に移動加圧するとシリンダーｂ２６内に充噴された液体２が加圧され開孔部ｂ２８を通り、吸入弁ｂ３１の通路ｂ３３から僅かに遊離したボールｂ３２を、ラビリンス効果及び液体圧力にて加圧し、吸入弁ｂ３１の通路ｂ３３方向に移動させる。その結果、吸入弁ｂ３１の通路ｂ３３を密閉し容器１側に逆流することを阻止する。そのため、加圧された液体２は排出弁ｂ３０を押下げ噴射液誘導管２５に送り出され、噴射孔１１から外部に噴射される。大気圧取り入れ口（図示せず）は微孔のため、容器１を倒立させても漏れ出ることはない。   Due to the negative pressure, the liquid 2 in the container 1 pressurized to atmospheric pressure is sucked from the liquid feeding pipe end b35 located in the container head 4. With this suction force, the liquid is charged into the cylinder b26. When the grip lever 14 is moved and pressurized in the left direction again in the drawing, the liquid 2 charged in the cylinder b26 is pressurized and passes through the opening b28, and the ball b32 slightly released from the passage b33 of the suction valve b31, The pressure is increased by the labyrinth effect and the liquid pressure, and the suction valve b31 is moved in the direction of the passage b33. As a result, the passage b33 of the suction valve b31 is sealed to prevent backflow to the container 1 side. Therefore, the pressurized liquid 2 is sent out to the injection liquid guide pipe 25 by pushing down the discharge valve b30 and is injected to the outside from the injection hole 11. Since the atmospheric pressure inlet (not shown) is a fine hole, it does not leak even if the container 1 is inverted.

図４は、手動式スプレー装置１０が正立用噴射経路５１及び倒立用噴射経路５２の２経路を具備することを示す説明図である。容器が正立状態、倒立状態及び傾斜状態の何れの状態でも容器内の液体を噴射することが出来る、また倒立状態にする事により液体が残っている限り無駄なく噴射出来る。   FIG. 4 is an explanatory diagram showing that the manual spray device 10 has two paths, an upright injection path 51 and an inverted injection path 52. The liquid in the container can be ejected when the container is in an upright state, an inverted state, or an inclined state, and can be ejected without waste as long as the liquid remains in the inverted state.

以上の構成要素からなる本手動式スプレー装置によれば、容器の構造を複雑化しても、正立時でも倒立時でも傾斜時でも円滑に噴射可能である。また、正立用噴噴射ポンプ１２及び倒立用噴射ポンプ１３の軸心は同軸に配置される構成のため、握りレバー１４や噴射孔１１を正立用噴射経路５１及び倒立用噴射経路５２の二経路で共有できる。そのため構造が簡素化されスプレー作業に支障の無い空間内でスプレー装置を作成することが可能となる。また、両ポンプの軸心を同軸に配置する構成は、生産段階での一体成型にも有利である。   According to this manual spray device comprising the above-described components, even if the container structure is complicated, it is possible to inject smoothly even when the container is upright, inverted, or inclined. Further, since the shaft centers of the upright injection pump 12 and the inverted injection pump 13 are arranged coaxially, the grip lever 14 and the injection hole 11 are connected to the upright injection path 51 and the inverted injection path 52. Can be shared by route. Therefore, the structure can be simplified and the spray device can be created in a space that does not hinder the spraying operation. Moreover, the structure which arrange | positions the axial center of both pumps coaxially is advantageous also for the integral molding in a production stage.
